[OMPI devel] socket usage

[Joachim Worringen]

Is there a formula to calculate the number of socket connections per 
node (S) that an OpenMPI application needs for running (via sockets) on 
N nodes with P processes each? I guess something like

S = P * (N-1)*P

but what about the daemons etc.? Let's assume only a single interface is 
used.

 thanks, Joachim
